Abstract: Various cartridge assemblies for surgical instruments are provided. Cartridge assemblies can include active sensors for applying stimuli to a tissue clamped by an end effector of the surgical instrument and a circuit configured to determine a tissue type of the tissue according to a change in the tissue parameter detected by the sensor resulting from a stimulus from the active element. Cartridge assemblies can also include physical features and/or stored data that identify the cartridge. Surgical instruments further can be configured to resolve conflicts when the physical features and/or stored data are not consistent with each other in their identification of the cartridge type.
